Scientific paper

The authors study an anisotropic simplicial minisuperspace model with a cosmological constant and a massive scalar field. After obtaining the classical solutions, they compute the semiclassical approximation of the no-boundary wavefunction of the universe along a steepest-descent contour passing through classical Lorentzian solutions. The oscillatory behaviour of the resulting wavefunction is consistent with the prediction of classical Lorentzian spacetime for the late universe.
